Title: Improvements in or relating to circuits for generating pulses of current or voltage
IPC: H03K3/16
Filed: 1948-04-19
Abstract: 661,377. Pulse generating circuits. PHILIPS ELECTRICAL, Ltd. April 19, 1948 [April 22, 1947], No. 10772/48. Class 40 (vi). In a pulse generator a capacitor is charged through a rectifier by a voltage derived from the anode circuit of a valve and is then discharged through a resistor and a biassed rectifier so that the grid voltage exhibits a pulse type variation, the capacitor discharging below the value of the biassing voltage applied to the rectifier. In the Figure, capacitor 5 is charged from the anode circuit via rectifier 4 and the transformer windings 2, 3 and subsequently discharges via resistor 6 and the rectifier 7 which is biassed by battery B3. Valve 1 conducts until the voltage across capacitor 5 falls below that of B3 when the grid voltage falls and due to the regenerative action of the transformer, windings 2, 9 drops almost at once to the value of battery B2, Fig. 2 (not shown). The grid voltage remains at this level until capacitor 5 charges to a voltage above that of battery B3 when the grid voltage rises and due to the regenerative action the valve conducts again. A pulse type variation of grid voltage and anode current is thus produced, the amplitude of the grid voltage pulse being determined by the voltage of batteries B3 and B2. A higher frequency signal applied to transformer 10 will be amplified by the valve during its conducting periods, the filters 12, 13 preventing amplified signal from being fed from the anode to the grid circuit via transformer windings 2, 9.

Title: Improvements in electric protective arrangements
IPC: H02H1/00
Filed: 1932-04-15
Abstract: 397,245. Protective cut-out arrangements. GRAY, J., Crown House, Aldwych, London.-(Allgemeine Elektricitats-Ges.; 2, Friedrich Karl-Ufer, Berlin.) April 15, 1932, No. 10867. [Class 38 (v).] In a polyphase protective arrange ment employing impedance relays ir each phase, the voltage winding being arranged to be energized only whei excess current flows in the corresponding phase, the neutral conductor o f the voltage coils is arranged to be con nected to earth only when an out-of balance current flows in the star connected current coils, this connection including a resistance or impedance of such a value that, when the said earth connection is completed, the voltage available for the energization of the voltage coils is reduced as compared with the voltage available, in the absence of the resistance or impedance, in about the same proportion as that in which the impedance of the system between the fault and the relaying point is increased with earth fault conditions as compared with the impedance in interphase fault conditions. As shown in the Figure, the three impedance relays r have current coils b fed from corresponding phases of the current transformers a in the protected line u, v, w and voltage windings c the circuits of which are completed at relay contacts d with excess current in the corresponding phases. The neutral point of the voltage windings c is normally not connected to earth but on the occurrence of an earth fault an out-of-balance current flowing in the neutral wire of the current transformers a energizes a coil f which closes a contact e to complete the earth circuit of the voltage transformers. Included in this earth circuit is a resistance w, which is of such a value as to compensate for the difference in impedance of the line in the case of earth faults and interphase faults, so that the time-lag of operation of the impedance relay is approximately the same for the same distance of the fault from the relaying point, independently of the type of such fault. Instead of energizing the voltage elements of the impedance relays directly from the line conductors they may be energized through transformers, Figs. 2 and 3 (not shown). The resistance w1 may be shunted by a suitable reactance to compensate for the drop in power factor on a double earth fault. The reactance of the voltage windings of the impedance relays may be compensated by seriesconnected condensers.

Abstract: 927,412. Making elliptical gears. DOWTY ROTOL Ltd. March 19, 1962 [March 24, 1961], No. 10909/61. Class 83 (2). In a method of making an elliptical gear a hollow cylindrical member 11 having external gear teeth 12 is heated to a desired temperature and placed between the platens 13, 14 of a suitable press which is operated to apply a radial inwardly-directed pressure in diametrically opposite directions to deform it into the required elliptical shape. A hub member (not shown) having an external form complementary with the elliptical bore of the gear 11 and an internal bearing within it offset from the intersection of its major and minor axes is suitably copper-brazed to the gear and the assembly subjected to a nitriding hardening process. The gear assembly may be used for slow-running devices or where the gears in mesh are only required to make one or less than one revolution. A particular application is in aircraft flying control systems where gears arranged on parallel axes permit the transmission ratio to vary from 2 : 1 at each end of a movement to 0.5 1 at the half-way stage.
